Magic Finger Science Experiment

Did you see this on Pinterest today?! WoW!
Happy Pi Day everyone!  Today is gorgeous outside in Ohio so we stayed outside longer and took out the colorful chalk!

Here's a fun science freebie that you can use!  It's the magic finger experiment!  This is where you sprinkle pepper in a bowl of water and you rub your finger with a soap bar.  Then you dip your finger to the surface of the water.  Watch what happens!  (The pepper moves away from the water)

Science behind this:
When you though your soapy finger to water, the surface tension of the water is lowered.  As the water flattens, the pepper that is flatting on top of the water repels to the outer edge of the bowl, like MAGIC! Click HERE or the picture for the free worksheet!
You can also do this experiment with milk and food coloring.  The food coloring will burst towards the outer edge as well when the soap touches the milk.  

Now I'm off to finish packing up two more rooms in the house!!  It's so sad to see my room and the whole house so BARE.  It's crazy to think I won't be living in my house (it's been12 years since we've moved) or even the state anymore!
